Abstract
A position inspection system includes a gripping unit that grips an object, a shooting unit that shoots an inspection image of the object gripped by the gripping unit, and a processor. The processor identifies a first rotational amount of the object from the proper position within a plane of the inspection image. The processor identifies, based on control information of the gripping unit, a correction angle between a direction in which a particular portion of the object is facing and a shooting direction of the inspection image. The processor identifies, based on the first rotational amount and the correction angle, a second rotational amount of the object from the proper position about the direction in which the particular portion of the object is facing.
